Zodariidae fromMediterranean Europe 9 Results Description of new species Zodarion montesacrense Bosmans spec. nov. (Fig. 1a–e) Type material. Holotype ) from Italy, Puglia, Gargano, Mat- tinata, Monte Sacro (N41°45’ E16°02’), 24.IV.2011, P. J. van Helsdingen leg.; deposited in NBCL. Etymology .The name of the species is derived from the type locality, adjective. Diagnosis. This small Zodarion species is a member of the pusio group as defined by Bosmans (1997) and is closely re- lated to Zodarion emarginatum (Simon, 1873). The species is easily distinguished by the terminally bifid tibial apophysis of the male palp. Description. Measurements: Male: Total length 1.54; proso- ma 0.82 long 0.62 wide. Colour (Fig. 1a): The holotype is recently moulted and the natural colours are not fully developed yet. Prosoma pale yel- lowish, margin, foveal spot and anastomosing striae darkened and eye region black; opisthosoma dark sepia, venter and oval spot above spinnerets whitish. Eyes: AM = 1 (0.69); AL = PL = 0.47; PM = 0.5; a = 0.38; b = d = 0.19; c = 1; d = 0.3; MOQ: AW = 0.91PW; L = 0.87 PW. Opisthosoma: with a row of 17 spines before the spinnerets, not much thicker than the normal hairs. Palp (Fig. 1b–e):Tibial apophysis longer than the tibia’s diame- ter with short pointed dorsal apophysis a longer, slightly cur- ved, terminally incised median apophysis and a shorter roun- ded ventral apophysis; median apophysis reversed U-shaped, distal branch pointed and longer than basal branch; embolus gradually narrowing, with tip pointed, in antero-ventral view with distinct concavity. Female: Unknown. Distribution. Only known from the type locality in Puglia (Italy). The species was mentioned as Zodarion sp. in IJland et al. (2012).

The species is dedicated to Roberto Pantaleoni, Director of CNR, Istituto per lo Studio degli Ecosistemi Sas- sari which supports and promotes faunistic studies in Sardinia. Diagnosis. Zodarion pantaleonii spec. nov. belongs to the italicum group of Zodarion . Males differ from other species in this group by the distal branch of the median apophysis being twice as long as the basal branch, equal to slightly longer in all other species (Fig. 2i); females by the trapezoid median plate in the epigyne (Fig. 2j–k). Description. Measurements: Male: Total length 2.0–2.4; prosoma 1.02–1.21 long, 0.71–0.90 wide. Female: Total length 2.7–2.8; prosoma 1.22–1.24 long, 0.84–0.86 wide. Colour (Fig. 2a–c): Prosoma yellowish brown with darkened eye region and greyish brown anastomosing striae; patellae pale yellowish, femora yellowish orange with pale base, other segments orange brown; opisthosoma sepia, venter for a small or greater part whitish. Eyes: AM = 1 (0.1); AL = 0.5; PM = 0.5; PL = 0.6; a = 0.5; b = 0.2; c = 1.3; d = 0.3; MOQ: AW = 1.1PW; L = 0.9 PW. Opisthosoma: With a of row of 10–22 bristles before the spinnerets, thicker and only slightly longer than the scatte- red hairs on the rest of the venter; in several specimens many bristles have been lost and in the two females only one and three bristles are present. Palp (Fig. 2d–g): Tibial apophysis elongated, slightly curved, longer than the tibia’s diameter, narrow from its base, with small denticule at prolateral margin, terminally strongly poin- ted; median apophysis with distal branch longer than basal branch, strongly pointed terminally; embolus abruptly narro- wing in distal third, terminally strongly pointed. Epigyne (Fig. 2j–k): With relatively large trapezoid median plate, clear white, contrasting with the lateral and anterior bor- ders of the epigyne. Vulva (Fig. 2l–n): Spermathecae oval, separated by twice their diameter. Distribution. Probably an endemic species of Sardinia (Italy).
